Resources Controlled By
- The Award Plug and Play BIOS has the capacity to
automatically configure all of the boot and Plug and Play compatible devices. This
capability is specifically designed for a Plug and Play operating system such as Windows
95. Choices are
Auto
(Default) and Manual.
Reset Configuration Data
- Reset Configuration Data: When set to Enabled, ESCD
(Extended System Configuration Data) is cleared. This setting will automatically be set
back to Disabled when the system reboots.
Enabled
and
Disabled
(Default).
IRQ3/4/5/7/9/10/11/12/14/15, DMA0/1/3/5/6/7 assigned to
- By default, all resources are
assigned to the PCI Bus except IRQs 3 and 4. If an ISA card requires a particular IRQ or
DMA channel, those resources should be set to Legacy ISA so that the PCI Bus will not try
to use them. Choices are
Legacy ISA
and
PCI/ISA PnP
.
PCI IRQ Activated By
- This sets the method by which the PCI bus recognizes that an IRQ
service is being requested by a device. Under all circumstances, you should retain the
default configuration unless advised otherwise by your system’s manufacturer. Choices are
Level
(Default) and
Edge
.
PCI IDE IRQ Map To
- Configures what type of IDE disk controller is in use. By default,
Setup assumes that you are using the on-board PCI IDE Controller and this option is set to
PCI-AUTO
. If you have equipped your system with an add-on PCI controller, changing this
setting allows you to specify which slot has the controller and which PCI interrupt (A, B, C
or D) is associated with the Primary and/or Secondary port. Most add-on IDE controllers are
configured to use INT# A for the primary and INT# B for the secondary.
On Board SCSI BIOS
- When set to
Auto
(Default), the system will automatically sense
the presence of any SCSI adapter that uses a Symbios SYM53C8XX SCSI chip:
SCSI adapter
has
its own BIOS on board:
uses adapter’s own SCSI BIOS
SCSI adapter
doesn’t have
its own BIOS:
uses SCSI BIOS built-in Mainboard BIOS
Disabling
, the onboard SCSI BIOS prevents it from being active in any way.
PCI Latency Timer
- This option sets latency of all PCI devices on the PCI bus. The
settings are in units equal to PCI clocks. Available settings are 0 ~ 248. The default is 80.
LOAD BIOS DEFAULTS
